I just spoke to the guy, and apparently the issue is a too high rate of insertions by multiple processes concurrently. If every process uses the same APC key to store, they conflict and only one of them wins and the other leave a "hole" in the memory space. This should not take the server down though. He says he's already working on improving this, and this should hit CVS soon (ie, before the end of the month). He also suggests that you try the current CVS version of APC to see if that already solves the taking down of the server. Could you perhaps try that? regards, Derick -- Components mailing list Components@lists.ez.no http://lists.ez.no/mailman/listinfo/components
