Topic: Another Error, causing Dead Server

PPP: no memory for vj compression.....


Any ideas?
Do I need more Server RAM in order to handle these E-mail services?

Yes. You might be able to get away with increasing your swap space but the system would be slow.

Memory is cheap, but don't use cheap memory. IMHO, memory is the most critical hardware component. We only use Kingston RAM, but any of the major brand name manufactures should be okay. Our min. confirguration is 64M.

You need more server RAM, or you need to tune the server to be less enthusiastic about delivering email.

Log into your server (user root, password the admin password), then run these commands:

cd /var/qmail/control
echo 2 > concurrencyremote
echo 2 > concurrencylocal
exit

By default qmail attempts up to 20 remote deliveries simultaneously, and if the messages are large, the network buffers can exhaust free memory.

The figures I have given are very conservative, if you notice any email slowdown (and I don't think you will) then you could try increasing them a little bit.

Please let me know how you get on with this change.
