What are the best settings for gallery2 (eg xcache.size etc) I'm using:

http://www.lolzing.com/Support/XCache/XCache%201.2.2%20Administration.htm

Here's what it caches:

Also, XCache segfaults when the gallery gets busy, any ideas how to stop that, should it be caching 18,000 items like /home/cityv4/g2data/cache/entity/6/7/67367-fast.inc

ty :)

if xcache doesn't work fine for you, i suggest you try APC or eaccelerator. APC and eaccelerator needed a long time before they got somewhat stable too.

> should it be caching 18,000 items like /home/cityv4/g2data/cache/entity/6/7/67367-fast.inc

at that specific path just 1, since it's just 1 file.
but generally yes, there are as many cached files in g2data/cache/ as you have items. (or rather x times as many files as you have items).

eAccelerator had the same problem, if APC works I'll post here. I also tried adding auto_globals_jit = off into php.ini as per
http://www.slantview.com/blog/slantview/apache2-php-5-x-xcache-load-segfaults-not-any-more

but that didn't help. It would be great to get a cache working rather than adding RAM. I'll keep working on it, Thanks Valiant :)

Sometimes I get those errors before the segfault. I tried clearing all caches.

http://plog.hlps.tcc.edu.tw/plog/post/1/2795 anybody understand that?

Also working on this here:

Weeks of head banging and it was in front of me the whole time. I assumed the customfield module is essential since its enabled by default and I never tampered with it. Disabled the module, segfaults gone.
