Check cachemgr -> General Runtime Information on info regarding fd-usage and the nuber of spare fd´s. If you get lot´s of : Warning : Your cache is running out of file descriptors ! in cache.log. Then you may need to increase them. Check the Squid FAQ on how todo this. ps: install and use the latest STABLE release. M.
