Symptoms

If a Tcl monitor encounters an error, it may exit with an assert which causes bigd to core.

Impact

bigd can core, which temporarily suspends monitoring while bigd restarts.

Conditions

This can occur rarely when Tcl monitors are in use (specifically, SMTP, FTP, IMAP, POP3 monitors).

Workaround

None.

Fix Information

Now, when a Tcl monitor encounters an error, it no longer exits with an assert, so bigd no longer cores.
