>
> When JniBasedUnixGroupsNetgroupMapping or JniBasedUnixGroupsMapping is used,
> we get segmentation fault very often. The same system ran 2.2 for months
> without any problem, but as soon as upgrading to 2.3, it started crashing.
> This resulted in multiple name node crashes per day.
> The server was running nslcd (nss-pam-ldapd-0.7.5-15.el6_3.2). We did not see
> this problem on the servers running sssd.
> There was one change in the C code and it modified the return code handling
> after getgrouplist() call. If the function returns 0 or a negative value less
> than -1, it will do realloc() instead of returning failure.
