Copying ithreads group as well. From: Daniel Rychlik Oh great an powerful PERL Oz I have just discovered a serious issue within the core
architecture of this beast of a program that I have written using
threads… I am using Thread::Queue to throttle resources from the jobs
that have to be done at any given time. This program, collects information from a database, maps a
drive using OLE calls, and copies the files to the destination drive and it
does this part well. The problem is, some of my servers are dial
up… I have no issues making modem calls but sometimes I get
disconnected during the copy phase which causes my threads to hold up and not
release its resource back to the queue for the next job… I am limited on resources for the jobs… Right now, I am simply passing the job off to a thread and
detaching it… If for some reason, like being disconnected from the
server, the thread hangs out there in lala land and never returns it resource
back to the resource queue for the next job, causing a major bottleneck in my
program. I am inquiring about a possible solution to monitor either
connection status to my destination server, or a thread timeout so that I can
catch the resource and put it back in the queue for the next job. Any suggestions would be wonderful and I would owe you money
for this one… Dan |
