Greetings, Anomy folk
After 9 months of perfect behavior, my anomy+sendmail box, a SunBlade 100
running Solaris 8 began to fail in wierd ways when receiving mail to a
large number of valid users.
The problem manifests itself by bouncing a mail to a valid user with
the error "user unknown." I would also see mail with a txt file
attachment be quarantined by my Sophos scanner, claiming to be
Digging into the sanitizer log, I saw
/usr/local/bin/sanitize: fork: Resource temporarily unavailable
So, I had apparently hit the max number of processes per user when
dealing with this large stream of mails. I fixed it by increasing the
maxuprc parameter in /etc/system and rebooting.
Hopefully this will benefit other anomy-on-Solaris users.
