>Description:
i am currently porting the OpenSource Database SAPDB (www.sapdb.org) to FreeBSD 5.

On FreeBSD5.0 most of the stuff runs fine now (see www.komadev.de/sapdb), But as i wanted to try it out on FreeBSD 5.1-Release,first of all most Of the programs a not working as expected. (lock ups etc)

A truss against these programms creates this syslogd entries:

Jun 16 23:49:04 devil kernel: Sleeping on "stopevent" with the following non-sleepablelocks held: Jun 16 23:49:04 devil kernel: exclusive sleep mutex sigacts r = 0 (0xc69a6aa8) locked @ kern/kern_synch.c:296 Jun 16 23:49:04 devil kernel: Sleeping on "stopevent" with the following non-sleepablelocks held: Jun 16 23:49:04 devil kernel: exclusive sleep mutex sigacts r = 0 (0xc69a6aa8) locked @ kern/subr_trap.c:248

A simple run of the programs does not create a log entry.

When i am using the libc.so.5 from FreeBSD5.0 within FreeBSD 5.1 all the Stuff is running fine again, all but python which is used within the DB, Then leading to an "__fpclassifyd" missing .so linker entry.

The progs are using the linuxthreads libs

Any help is greatly apreciated.

Thanx Kai

>How-To-Repeat:
 - Download sapdb build-421 and the config-421 from www.komadev.de/sapdb follow the installation instructions
 - After installation source the file /usr/local/sapdb/sapdb.env
 - Remove /usr/local/sapdb/depend/lib/bsd50 from LD_LIBRARY_PATH (this is the current workaround)
 - now execute dbmcli or any other tool from /usr/local/sapdb/depend/bin
>Fix:
 - Using FreeBSD5.0 libraries in LD_LIBRARY_PATH (bad hack!)
