Hi I am running last 2.6STABLE16 version of squid on Centos5 linux. But after some seconds squid is crashing with those erorrs #0 0x002c37a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 #1 0x003047a5 in raise () from /lib/tls/libc.so.6 #2 0x00306209 in abort () from /lib/tls/libc.so.6 #3 0x00338a1a in __libc_message () from /lib/tls/libc.so.6 #4 0x0033f2bf in _int_free () from /lib/tls/libc.so.6 #5 0x0033f63a in free () from /lib/tls/libc.so.6 #6 0x08082639 in helperRequestFree (r=0x404ff4) at helper.c:1125 #7 0x080830bf in helperHandleRead (fd=7, data=0xa0e8e40) at helper.c:776 #8 0x0806dc49 in comm_select (msec=326) at comm_generic.c:264 #9 0x08095a49 in main (argc=2, argv=0xbff07464) at main.c:839 After this I have try the 2.6STABLE12 version, but nothing change #0 0x002c37a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 #1 0x003047a5 in raise () from /lib/tls/libc.so.6 #2 0x00306209 in abort () from /lib/tls/libc.so.6 #3 0x00338a1a in __libc_message () from /lib/tls/libc.so.6 #4 0x0033f2bf in _int_free () from /lib/tls/libc.so.6 #5 0x0033f63a in free () from /lib/tls/libc.so.6 #6 0x08082535 in helperRequestFree (r=0x404ff4) at helper.c:1125 #7 0x08082f9c in helperHandleRead (fd=6, data=0x9d13da0) at helper.c:776 #8 0x0806dc56 in comm_select (msec=10) at comm_generic.c:264 #9 0x08095839 in main (argc=2, argv=0xbfe8f8b4) at main.c:837 Also I have try the squid-2.6.STABLE6 from centos repository, and complile it with the same parametrs and it works fine without any errors.
