I am trying to track down the cause of some errors that have been occurring on a number of our servers using LDAP. We have noticed that when a certain LDAP group exceeds 65 users we begin seeing glibc errors for users in the group. Users that are not in the group do not exhibit this behavior.
We have seen this issue on machines running Centos 4.5 x86 & x86_64 with glibc-2.3.4-2.36 and RH4 x86_64 running glibc-2.3.4-2.25. We are running Fedora Directory Server 1.0.4 on Centos 4.5. We have added a 3rd FDS slave and turned up debugging but have not seen anything that appears to be relevant in the logs on the 3rd slave. This problem is not a 65 user limit as we have other groups with well over 65 members that do not display this behavior. We also created a new group with identical users and it did not display this problem. 1) With 66 users in the massweb group [EMAIL PROTECTED] ~]# getent group massweb *** glibc detected *** free(): invalid next size (normal): 0x09a225b0 *** Aborted 2) After removing any user from the massweb group to reduce the total members to 65 [EMAIL PROTECTED] ~]# getent group massweb massweb:x:3016:afaxon,ashairza,ccrump,jhorowit,mmarum,morendai,usmall,adroffne,afaxon,amurphre,aoliver,ayellipe,bdonohue,bdunn,beckert,blarsen,bwphilli,catanis,ccrump,chaynes,clyons,cwong,dbarber,dmuse,dnicol,edougher,egallant,ekubosia,evizcain,feeddrop,gtulonen,halokush,hbraverm,jbartus,jbrown,jhobbs,jking,jlederma,jpecora,jthayer,kbalbedi,kbeam,kginn,mbuonfig,mcrawfor,mlarsen,mlong,mwalsh,osedano,proche,prondeau,pweinber,rhorriga,rkersey,rskutins,sasaro,sbrodeur,sculver,smoriart,support,swestenh,tbaltimo,torgelfi,usmall,vvalenti Has anyone encountered a similar problem?
