[mapserver-users] problem reading log/debug

[jim white]

Daniel,

Great - the fflush worked. The OS is Debian Etch 64. I am using 
php/mapscript.

Perhaps you recall that I had a similar problem with the same server 
with PHP/mapscript and calling flush caused a segmentation fault to show 
in the apache error logs. Perhaps there is something similar I could 
experiment with that would flush mapscript output?

Um... the only reason I can think of for this to happen would be if your 
mapserv processes hang and never close/flush the log output. Actually, 
are you using the mapserv CGI or MapScript? On which OS is this happening?

If you built from source, you could possibly work around the problem by 
adding a fflush() call in msDebug() after the msIO_vfprintf() line. That 
could keep you going but would not solve the key issue which seems to be 
that your processes possibly hang or something like that. We'd need more 
info to help with that.
