Hi, After upgrading to clamd 0.90 I found that clamd doesn't work well with libpthread.so.2. Using libmap.conf entries for libthr.so.2 or libc_r.so.6 worked fine. With both thread libraries clamd works as it should. The effect with libpthread is that clamd works very very slow. It's only able to scan 1-2 files in 5 seconds instead of 400-500 in the same time with libthr/libc_r. A ktrace shows the following behaviour: clamd 0.90 and libpthread.so.2 1735 clamd RET fork 0 1735 clamd CALL kse_release(0xbe7eac20) 1735 clamd CALL kse_wakeup(0x9e4678c) 1735 clamd RET kse_wakeup 0 1735 clamd CALL kse_release(0x9ea3f10) 1735 clamd RET kse_release 0 1735 clamd RET kse_release 0 1735 clamd CALL kse_release(0x805df4c) 1735 clamd RET kse_release 0 1735 clamd CALL kse_release(0x9eabedc) 1735 clamd RET kse_release 0 1735 clamd CALL kse_release(0x805dedc) 1735 clamd CALL kse_wakeup(0x9e4670c) 1735 clamd CALL kse_release(0x9eabedc) 1735 clamd RET kse_release 0 1735 clamd RET kse_wakeup 0 1735 clamd CALL kse_wakeup(0x9e4680c) 1735 clamd RET fork 0 1735 clamd CALL kse_wakeup(0x805740c) 1735 clamd RET kse_wakeup 0 1735 clamd RET kse_release 0 1735 clamd CALL kse_release(0x9ea7f10) 1735 clamd RET kse_release 0 1735 clamd CALL kse_release(0xbef61c10) 1735 clamd CALL kse_release(0x805dedc) 1735 clamd CALL kse_wakeup(0x805740c) 1735 clamd RET kse_wakeup 0 1735 clamd RET kse_release 0 1735 clamd CALL kse_release(0xbec30f50) 1735 clamd CALL kse_wakeup(0x9e4678c) 1735 clamd RET kse_wakeup 0 1735 clamd RET kse_release 0 1735 clamd CALL kse_release(0xbe8fbb90) 1735 clamd CALL kse_wakeup(0x9e4670c) 1735 clamd RET kse_wakeup 0 1735 clamd RET kse_release 0 1735 clamd CALL kse_release(0x9ea7f40) 1735 clamd CALL kse_wakeup(0x9e4680c) 1735 clamd RET kse_release 0 1735 clamd RET kse_release 0 1735 clamd RET kse_wakeup 0 1735 clamd CALL kse_release(0x9ea7ed0) 1735 clamd CALL kse_wakeup(0x805740c) 1735 clamd CALL kse_release(0xbef61bd0) 1735 clamd RET kse_wakeup 0 1735 clamd RET kse_release 0 1735 clamd CALL kse_release(0xbee50bd0) 1735 clamd CALL kse_wakeup(0x9e4678c) 1735 clamd RET kse_wakeup 0 1735 clamd RET kse_release 0 After ~10000 lines which show all like this, clamd actually opens and scans something, then another ~10000 lines follow ... I guess it's a bug in libpthread, but it really doesn't work fine with this lib. Or is it bad programming in clamav ? Any comments ?
