Ubuntu 20.04, Dovecot 2.3.7.2, SpamProbe v1.4d. For the past weeks my
sieve filters that call spamprobe have been crashing out for some users.
I have a dozen similar server setups and this is not happening on any
of the other servers and it was working just fine for a year up until
recently. This particular server is quite busy. There is plenty of disk
space and inode usage is about 2.5%. Permissions look the same as on
the other servers.
I'm hoping someone might have a suggestion as to the cause of this?
