I have this very simple program that executes an external program, reads its output and prints it (the program is "date"). The readings is done with pipes.
The problem is that memory usage constantly increases over time. Profiling does not show garbage collection of any sort.
Huh. Thank you; I'd observed that behavior in one of my programs but hadn't sat down to figure out why yet, mostly because I have a workaround: if you cap the heap (+RTS -M...) it *does* do GC. Which makes it sound like something I don't know how to debug. :/ -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
