Hello I'm running an old version of Zope which is required by our corporate design using also an older version of the CMS Silva: Linux Distribution: Red Hat Enterprise Linux Server release 5.5 Linux Kernel: 2.6.18-194.8.1.el5PAE Zope: 2.8.9.1 Python: 2.3.6 (with several modules, like: ldap, pil, mysql, pyxml, ...) Silva: 1.5.13 My problem ist that my zope server hat timeouts on displaying pages after a while that it has been started (currently this "while" is approx. 15 minutes). The only thing that helps is restarting zope. By accident I discovered about two month ago, that running an "strace -f" on the zope process, "reactivated" it... so I could live with this hack until yesterday. Now I'm running "strace" permanently (with all the disadvantages) and zope works "fine" for about 1 to 1.5 hours. Here is a short recurring output of "strace":
[pid 13408] <... futex resumed> ) = 0 [pid 13406] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> [pid 13405] futex(0xbcc12c0, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> [pid 13408] futex(0xbcc12c0, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> [pid 13407] <... futex resumed> ) = 0 [pid 13405] <... futex resumed> ) = 1 [pid 13408] <... futex resumed> ) = 1 [pid 13405] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> [pid 13408] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> [pid 13406] <... futex resumed> ) = 0 [pid 13406] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> [pid 13407] futex(0xbcc12c0, FUTEX_WAKE_PRIVATE, 1) = 1 [pid 13405] <... futex resumed> ) = 0 [pid 13407] futex(0xbcc12c0, FUTEX_WAKE_PRIVATE, 1 <unfinished ...> [pid 13405] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> [pid 13408] <... futex resumed> ) = 0 [pid 13407] <... futex resumed> ) = 1 [pid 13407] futex(0xbcc12c0, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...> [pid 13405] <... futex resumed> ) = -1 EAGAIN (Resource temporarily unavailable)
I need definitively help... Any idea? Thx, Michele -- ETH Zürich Michele Marcionelli IT Support Gruppe D-MATH HG G 32.1 Rämistrasse 101 CH–8092 Zürich michele.marcionelli@math.ethz.ch http://www.math.ethz.ch/~michele +41 44 632 6193 Telefon +41 44 632 1354 Fax
