Hi Jan-Frode and the others that have replied,
Your suggestions have helpt us enormously. I have increased SxVMemLimit
WOWorkersCount (PREFORK), and this made sogo much more responsive
generally. So far: no lockups, but this has only been running half an
hour or so.
I have also increased the max_connections to our mysql database server,
and will shortly also put your script on the server.
For now, life seems better again... But I don't want to cheer too early...
Thanks for your valuable input so far!
MJ
