[Spread-users] Send_new_packets: created packet 16 already exist 2

[Matt Garman]

We've experienced some random spread crashes recently.

In the log, we have the following message:

[Thu 01 May 2008 23:01:52] Send_new_packets: created packet 16 already exist 2
Exit caused by Alarm(EXIT)

I found another post on this in the archives, but it doesn't help
much: http://marc.info/?t=111651309700001&r=1&w=2

We have modified some of the #defines for spread, but not
recently---we've been running with the same parameter set for well
over a year.  But only recently are we seeing this issue.

I don't know if it's related, but I'm also seeing the following in
the logs:

The "BUG WORKAROUND" messages occur more often, maybe two to five
times a month, but they are not always correlated with a crash.

Any help would be much appreciated.

Thank you,
