I have the same problem mentioned in "1 login -> 20 verifications" - Apache child processes segfault when mod_auth_sasl is loaded.
I have done some investigations as follows:
1/ You don't have to actually *use* mod_authn_sasl, just loading the module is enough to start the segfaults.
2/ It doesn't seem to affect the operation of Apache, requests get serviced as usual. I suppose that the child is quickly replaced by another one.
3/ I have tried version 1.1 and version 1.0.2 and they both do it.
4/ I have tried using "apxs" to build mod_authn_sasl (to make sure that the CFLAGS etc are consistent) but no change.
5/ It seems to depend on the load on the server. One of our machines runs our main webserver and a Vbulletin forum, that one segfaults regularly and in "batches"; the other one runs our extranet and it segfaults much less.
Using Apache "2.2.3-43.el5.centos" on Centos 5, on two different machines.
Loading the module with "LoadModule authn_sasl_module modules/mod_authn_sasl.so"
