Failed Passenger startup with high number of group memberships

[ledo42]

Hi. There is a group limitation of the os user used in passenger's user switching feature. If the user exceeds 1024 group memberships, passenger will not start and log:

 [ E 2025-06-26 10:10:41.5457 80006/Tg age/Cor/App/Implementation.cpp:218 ]: Could not spawn process for application /var/local/xxxx/staging/current: getgrouplist(xxxx, 115) failed: No such file or directory (errno=2)

Since the linux limit is normally 65536 (NGROUPS_MAX), it would be great to have an config option to raise the limit for passenger for certain applications.
