how to increase minumal number of connexion (error Can't connect to freetds)

Hi,

I am using mod_dbd of apache to create a pool connexion with freetds as driver (Sybase).

I get error in my error_log of apache when I am increasing DBDMin connexion (only 10)

[Tue Jan 03 20:54:44 2012] [error] (20014)Internal error: DBD: Can't connect to freetds:
[Tue Jan 03 20:54:44 2012] [error] (20014)Internal error: DBD: failed to initialise
[Tue Jan 03 20:54:44 2012] [crit] (20014)Internal error: DBD: child init failed!
[Tue Jan 03 20:54:45 2012] [error] (20014)Internal error: DBD: Can't connect to freetds:
[Tue Jan 03 20:54:45 2012] [error] (20014)Internal error: DBD: failed to initialise
[Tue Jan 03 20:54:45 2012] [notice] child pid 23721 exit signal Segmentation fault (11)


I try to see in freetds log what happened but I don't realy understand...
I see the error " dblib.c:7981:20017: "Unexpected EOF from the server"


If anyone has an idea it will help me!


Thanks,
