Hello Gurus, I am sorry to send this question, but my search could not generate anything useful. ---------------------------------------------------- Server HP DL380 with 1GB RAM 72GB ULTRA FAST SCSI RHES -3 # uname -a Linux BM 2.4.21-15.ELsmp #1 SMP Thu Apr 22 00:18:24 EDT 2004 i686 i686 i386 GNU/Linux # squid -v Squid Cache: Version 2.5.STABLE3 ---------------------------------------------------- I am getting below error from the cache.log. Tried to modify the config but did not help. 2005/04/12 17:25:27| Config 'request_header_max_size'= 10240 bytes. 2005/04/12 17:25:28| Request header is too large (11680 bytes) 2005/04/12 17:25:28| Config 'request_header_max_size'= 10240 bytes. 2005/04/12 17:25:28| Request header is too large (12287 bytes) 2005/04/12 17:25:28| Config 'request_header_max_size'= 10240 bytes. My squid.conf says. ---------------------------------------------------- # cat squid.conf | grep request_header_max_size # TAG: request_header_max_size (KB) request_header_max_size 10 KB and on top of this I am also running out of file descriptors. I tried to increase it manually to ulimit -HSn 65534 but it changes back to 1024. # ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) 4 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) 10240 cpu time (seconds, -t) unlimited max user processes (-u) 7168 virtual memory (kbytes, -v) unlimited What more should I do? Please help. Regards, Rikunj Patel
