Dear All, Recently, I chose to install and run Squid 3.2.1 on Debain Weezy/SID (64 bit) with 4 workers At the beginning every thing went well, but when the system goes under loads of 20 users (more or less) I lose workers sequentially until there went no kids to process the requests. In this time I have to restart the squid to solve the problem temporarily. The cache log shows following error (part of the log): 2012/10/03 09:45:02 kid1| Loaded Icons. 2012/10/03 09:45:02 kid1| Reconfiguring Squid Cache (version 3.2.1)... 2012/10/03 09:45:02 kid1| Closing
