Re: [BackupPC-users] Can't Fork Crash on Nexenta (Solaris)
I am running BackupPC 3.2.0. The line where it fails is:
if ( !defined($pid = open(CHILD, -|)) ) {
So it looks like it is attempting to fork...

Fork Crash on Nexenta (Solaris)]:
On Nexenta (which is essentially an OpenSolaris derivative), I seem to have
issues where BackupPC crashes every once and a while. When it crashes, the
log says:
Can't fork at /usr/share/backuppc/lib/BackupPC/Lib.pm line 1340.
Any ideas how to prevent this?

errm, have less processes running on your machine? What errno is that? Line
1340 contains a Perl 'return' statement, so that's strange (since you didn't
mention it, you must be using BackupPC 3.2.0beta0, because that's the version
I happened to check). Which log file? How come BackupPC writes something to
the log if it crashes? BackupPC doesn't even *try* to fork via Lib.pm (only
BackupPC_{dump,restore,archive} appear to use that), and failures to fork in
the daemon are certainly not fatal (except for daemonizing on startup).
Very strange.
Oh, and we know what Nexenta is. That's the part you wouldn't have needed to
explain.

The usual (perhaps only?) reason for not being able to fork is that you
have run out of resources or hit an OS-imposed limit
(memory/processes/file descriptors, etc.). Can you raise those limits
for the backuppc user?
