I have a long-running Gnu Radio application--my VLF sid receiver. It seems to "wedge" after a few days of flawless operation.
The application uses an audio source, and an audio sink, but usually the source and sink are on two different sound cards. The application uses a number of WxGUI widgets, and was generated using GRC. I don't see any evidence for a memory leak, the app reaches stable virtual and resident-set sizes fairly quickly, and they don't change. There's no evidence for a file-descriptor leak (checked /proc/XXXX for each of the 3 processes involved, and everything looks good). No kernel error messages (and this application behaves this way across different distributions of Linux--both Ubuntu and Fedora show this problem). Next time it happens, I'll force a core dump, and see if I can see where it's getting hung. But it's most puzzling, and a little worrying. I really need this app, and ones like it to run essentially indefinitely, doing what they do. If anyone has any kind of clue, and wants the code (most of it produced in GRC), please let me know.
