$ su -c "scodb -w" Password: dumpfile = /dev/mem namelist = /unix stunfile = /etc/conf/pack.d/scodb/defs/stun.def varifile = /etc/conf/pack.d/scodb/defs/vari.def PID 2CBF: scodb -w scodb:1> maxexecargs=100000 100000 scodb:2> q $ getconf ARG_MAX 1048576 This does not eliminate the issue. Also tried: $ getconf ARG_MAX 16777216 Note, I have no idea that ARG_MAX is or is not relevant. This documents something I did try based on a page that came up in searches: https://www.in-ulm.de/~mascheck/various/argmax/ [osr5] Bela Lubkin points out: The limit on SCO OpenServer 5.0.x is set by 'unsigned int maxexecargs = 1024*1024;' in /etc/conf/pack.d/kernel/space.c. It can also be changed on a live system with the `scodb` kernel debugger: # scodb -w scodb> maxexecargs=1000000 scodb> q (0x1000000 = 16MiB.) This is the max size of a new temporary allocation during each exec(), so it's safe to change on the fly. Exceeding the limit generates a kernel warning: WARNING: table_grow - exec data table page limit of 256 pages (MAXEXECARGS) exceeded by 1 pages WARNING: Reached MAXEXECARGS limit while adding arguments for executable "ls" Some `configure` scripts trigger this message as they deliberately probe the limit. Raising `maxexecargs' will not fix this as the probe will simply try harder. -- Kevin R.
