Hi,
After downgrading to the 4.0.15 provided by Mandrake, we found a more explicit message : cannot found xxx function, which was one of our UDF.
we recompile the UDF with the extern "C" (not needed on our dev. server, which is strange...), and everything is fine now.
When one query :
INSERT INTO func VALUES('myfunc_xxx',1,'libudf_cos.so','function');
are the .so tested and the function tested/loaded ? or do we have the restart the server ?

Hello,
This morning I got a crash from two mysql servers (one master, one slave). The stack trace is the following on both :
0x8071f44 handle_segfault + 420

0x82a4864 __libc_start_main + 212
0x8048101 _start + 33
As far as I understand this, is that I've got something wrong with the User Definable Function. Am I right ?
We added the UDF on friday, on everything seems going well, but not this morning. Any ideas where I should investigate ?
