There's no built-in limit, everything is expandable lists. However,
you'll certainly run out of memory at some point, and searching linked
lists degrades in performance as they get larger, so there's certainly
limits somewhere. I highly doubt anyone has come close to 50k exports
before.
You're backtrace is parsing the config file, so maybe large config file
parsing becomes slow?

Dear maintainer，
Does ganesha have a limit on the number of nfs share?
Recently I attempted to create 50 thousand nfs shares and it
turned out the debus server thread got stuck after creating about 20K
shares.
Also the commad “ganesha_mgr show exports” got no reponse and
finally timed out. See the below detailed result.
Could you please help take a took and give your valuable advice?
Thanks a lot.
Attahed the backtrace below.
