I couldn't find any sufficient answer to this. Our server load has be 10+ during the busy times of the day - I'm currently using 1.1.10 here's a copy of the error:

  • 2MB for php script is not that high.

    You should increase it.
  • I had it on 128M then reset it for no limit for php memory limit. I have quad intel xeon processors 2133.541 MHz - 4 gigs of RAM.
  • Do you have APC or other opcode cache enabled?

    Do you have a very customized forum? I'm wondering about plugins that might be interfering with your speed. If you don't have any plugins enabled, it could also be worthwhile doing an upgrade to Vanilla 2.
  • My server guys at hostgator raised the RLimit - it seems to have helped.

    One quick fix on a lot of Vanilla 1 forums is to turn off whispers. This makes your discussion list queries much much simpler.
  • I don't think turning off whispers would go over very well on his forum.

    Hi Jamie!!

    Also, the problem is still occurring, and it appears to be asking for more memory. Same function as before.

    How about an upgrade to Vanilla 2? Whispers are turned into private conversations during the conversion.
  • I wonder if memcached modifications might help if Vanilla 2 doesn't? Or some other form of caching? I've no idea what's in Vanilla 1.x these days, so I can't much help there myself.
  • a new error seems to have started cropping up now, plus we've got a halfway meaningful error message too.
