php sessions problem
On a RHEL server, PHP 4.3.2, Apache 2.0.4, Plesk 7.5.3
Suddenly in the last couple of days sites which depend on sessions intermittently fail with a "Fatal error: session_start(): Failed to initialize storage module. in site/page.php on line 3". Sometimes a reload corrects the problem, sometimes it seems to require an Apache restart.
All worked correctly before (server ha sbeen online 1.5 years). It seems to get worse mid-day, which might suggest a load issue. Server load typically is < .15, but spikes as high as 1.15 (dual xeon 2.4)
I've tried googling, but only come up with stuff that doesn't pertain...
