I'm running RHEL 4 AS update 3 with all current errata and Networker 7.3
build 190 on the client and server. On one client I noticed the backup
failed because the server couldn't connect. Checking the client I saw
that nsrexecd wasn't running and the following was logged in daemon.log:

*** glibc detected *** double free or corruption (out): 0xb400af28 ***

The /nsr/log/daemon.log file has a time stamp that exactly matches when
a backup was supposed to start and I _assume_ that it was nsrexced that
crashed with the above error, not some thing else like the save exec.
This does not appear to be something that frequently happens. This same
client did complete a full backup during the prior cycle without any errors.

Anyone else seen similar either on RHEL or with other UNIX builds?
