Thierry,
This is in conjunction with service request 36150044. I do not have a specific
patch reference, but EMC is referencing this savegrp bug by the code NW120811.

Stanley,
Any patch reference for the patched savegrp.exe on top of 7.5.3.1 Build 533 ?
I have an opened case with emc now but my contact cannot located
patched savegrp bin (for winX64)
Thanks

Frank,
Considering the many NetWorker server configurations out in the field, expecting EMC's software testing to uncover every possible issue on every platform with every OS version and every hardware driver is unrealistic. I suspect that EMC does is test the most common configurations in their software certification efforts, which gives rise to the potential for errors to occur on less common platforms.
I too am one of the people who is having trouble with 7.5SP3 (on a Red Hat Linux AS 32-bit)
running on a Dell 2950 with a Qualstar tape library that has four LTO-3 tape drives in it. I am
running build 533 and the new savegrp binary, but I still find one core dump file per day in
/nsr/cores/savegrp and my daily cron that runs "savegrp -O" continues to generate
output like this …
4690:savegrp: puss-index-backup waiting for 113 job(s) to complete
4690:savegrp: puss-index-backup waiting for 81 job(s) to complete
4690:savegrp: puss-index-backup waiting for 74 job(s) to complete
4690:savegrp: puss-index-backup waiting for 1 job(s) to complete
*** glibc detected *** corrupted double-linked list: 0x0984ff60 ***
/bin/sh: line 1: 13098 Aborted /usr/sbin/savegrp -O -l full -G
puss-index-backup
I tried the suggestion of running a trace on savegrp, but I had no clue of what
I was looking at in the output. I am wondering if anyone else with 7.5SP3 is
getting savegrp core dumps. In case you don't know, NetWorker stashes core dump
files in /nsr/cores. If your NetWorker server is generating savegrp core files
and you haven't opened a case with EMC about it, please consider doing so. The
more core dump files EMC has, the more likely they can uncover the cause of the
problem and fix it. What is also very confusing to me is that there seems to be
no pattern for what time of day these core files are generated on my server.

My goodness! All that time in development, testing by QA, I assume there was a
beta program as
well... and still it takes three fixes to get it to operate as it goes out the
door? That is
depressing news.
Perhaps EMC needs to look to their customers who are reporting these problems
and provide
incentives to them to take part in a beta program since it appears their own QA
group is not
quite up to the task.

We had some problems with 7.5.3 to begin with when we installed build 514.
Groups of Oracle clients not finishing properly (hanging).
EMC then released build 531 and few days later build 533. We installed
NetWorker 7.5.3.1 build 533 and our problems got even worse.
EMC then released a patched version of savegrp.exe build 533. After installing
that patched savegrp.exe binary we have not had any problems.
NetWorker 7.5.3.1 build 533 with patched savegrp.exe binary seems to be stable
and good.

What ulimit settings are you using and how many clients are you backing
up?
Here's what I have …
[root@puss nsr_scripts]# ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
pending signals (-i) 1024
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 143360
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
Your's looks like Solaris 10, but this is on 9 (SPARC):
# ulimit -a
core file size (blocks) unlimited
data seg size (kbytes) unlimited
file size (blocks) unlimited
open files unlimited
pipe size (512 bytes) 10
stack size (kbytes) 8192
cpu time (seconds) unlimited
max user processes 29995
virtual memory (kbytes) unlimited
The two groups that were abending had 41 and 25 clients each (not huge)
and we have a little over 100 clients total. However, the old ulimit
settings (which I don't recall) were from the original Solaris 8
installation back in 2003 (Networker 6.1). So, they weren't exactly big.
