Actually I should correct the record here -- the issue I ran into on Solaris actually turned out to be due to building against a rather old Solaris 8 patch level.  Rebuilding against a newer patch level seems to have stabilized this.  The instability was in the Apache core in this case, not in auth_ldap. I was wrong yet again. My first issue with Apache 1.3.28 on Solaris 8 is not auth_ldap related -- but it is not a patch level issue.  I can get it to hang quite easily with 'ab' with a 25K static HTML file and 50K requests with concurrency of 64.  I can still get Apache 1.3.28 to hang on Solaris 8 with lower concurrencies, but less easily.  I cannot get it to hang, however, if I increase MaxSpareServers from 10 (the default) to 15. Once that was resolved, however, then I discovered that Apache 1.3.28 (EAPI_MM) with auth_ldap 1.6.0 (with shared memory cache) will hang just like Apache 2.0.47 when the LDAP cache's entry count is exceeded, i.e. while trying to purge the cache. I guess the solution is just to set the cache big enough for now... -- Jess Holle
