Hi, Well, It's only 2 hours of on line testing, but seems that the recompilation and upgrade to apache-1.3.33 I did with "-g" to get debug info on coredumps solved the problem....
I used exactly the same configure options on apache,mod_ssl and mod_perl (I used the same shell script, in fact) Now I don't know what caused the problem first place, but now seems ok. I taked in account that first time I compiled all on a shell with "en_US" locale, and now I used one with "en_US.UTF8". May the locale used in the shell to compile apache+mod_perl affect the final executable in some way? The server has to deal with UTF8 info coming from/going to a SQLServer backend...
