Re: dumpers exiting with signal 11 in version 2.4.3?
2003-01-05 13:31:56
I have more information on this problem.
I see these messages in the 'amdump' file:
dumper: logfile.c@202: memory allocation failed (28 bytes requested)
dumper: debug.c@345: memory allocation failed (22 bytes requested)
The 'debug.c' message is repeated many times.
I ran a periodic 'top' during last night's backup, and I found
that the dumper process got into a loop and quickly used up all
the memory. Here is a report just before it died:
PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND
23204 amanda 25 0 2579M 2.5G 808 R 92.7 74.5 8:35 dumper
The start of the looping appears to have coincided with a tape
change. Note that I use chg-zd-mtx and ammt.
Any ideas?
Thanks!

Oops. :-)

What OS?

They should be in your Amanda debug directory, e.g. /tmp/amanda. You
should be able to find out with:
amadmin xx version | egrep 'AMANDA_DBGDIR|AMANDA_TMPDIR'
We really need to find them and run a debugger to get a traceback to
figure this out.
