Amol, I'm not sure this question reached the list, would you forward it please ? Further, I see the following trace caused kernel panic: Stack traceback for pid 5518 0xffff810092cfae80 5518 5477 1 2 R 0xffff810092cfb180 *java rsp rip Function (args) 0xffff810079a1bd38 0xffffffff805a5a5f sock_get_ops+0x1f (0x0) 0xffff810079a1bd80 0xffffffff8820cc46 [ad]ad_layer_revert+0x56 (0xffff810075077000) 0xffff810079a1bdb0 0xffffffff8820cd21 [ad]ad_layer_release+0x11 (0xffff810075077000) 0xffff810079a1bdd0 0xffffffff805a4e4b sock_release+0x5b (0xffff810075077000) 0xffff810079a1bdf0 0xffffffff805a5ce6 sock_close+0x26 (0xffff810075077050) 0xffff810079a1be10 0xffffffff802857e8 __fput+0x178 (0xffff81009b69d100) 0xffff810079a1be50 0xffffffff80285836 fput+0x16 (invalid) 0xffff810079a1be60 0xffffffff805a648c sys_accept+0x1dc (invalid, 0xfd7fe8b4, 0xfd7fe8b0) 0xffff810079a1bf40 0xffffffff805c0f43 compat_sys_socketcall+0xa3 (invalid) 0xffff810079a1bf80 0xffffffff80220452 ia32_sysret (invalid, invalid, invalid, invalid) Thanks in advance, Timir -----Original Message----- From: Timir Hazarika (thazarik) Sent: Tuesday, November 17, 2009 5:21 PM To: 'users@tomcat.apache.org' Subject: Tomcat 6.0.20 Causes Kernel Crash on Linux Folks, Are there any known memory issues with tomcat 6.0.20 ? This build causes a kernel panic on my linux box with Java 5. I'd been using 6.0.18 without any issues on the same configuration. http://markmail.org/message/mrpgvn4mqvyrq64a reports a memory leak, though I don't have enough debugs to say it matches mine. All I have is: BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000 printing eip: c05d9144 *pdpt = 000000002db52001 *pde = 0000000000000000 Oops: 0000 [#1] This problem is consistently reproducible on 6.0.20, and magically disappears upon switching back to 6.0.18. What am I missing ? Thanks in advance, Timir --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
