[rt-users] RT 3.8.7 fails to send email sometimes - cannot allocate memory?

[Chris Herrmann]

Ok, postscript: I haven't seen the problem occur in the week since making
the change. Memory usage on the box hasn't really changed at all, but the
error messages and the symptom have ceased and performance is still great so
currently looks like case closed, thankyou!

Regards,

Chris
