What does the following return?

sysctl proc.$$.rlimit.maxlwp.soft proc.$$.rlimit.maxlwp.hard

Also does the following help when its in that state (replace "doas"
with your preferred run as root command, but note that $$ needs to be
the pid of the shell in which you are trying to run svn/git :)

doas /sbin/sysctl -w proc.$$.rlimit.maxlwp.soft=2048
proc.$$.rlimit.maxlwp.hard=4096
