I'm working on a long running application without GUI. My problem is, that mono uses an increasing amount of memory until it crashes after ~2 weeks.
Here is a example output of "top" after a few days: 26225 xxxx 16 0 5360 1540 1336 S 0 0.0 0:00.01 bash 1478 xxxx 16 0 373m 151m 6088 S 0 1.9 0:35.80 mono 608 root 18 0 23284 7968 4760 R 0 0.1 0:00.07 apache2 My first thoughts were some kind of memory leak caused by me. To track them down I downloaded the trial version of ANTS Memory profiler for Windwos and tracked the memory consumption over a few hours. Surprisingly there was no memory leak. The Process started with ~20mb of virtual memory, the real memory usage was the whole time less than 1mb. The virtual memory did also not increase the whole time. To get an approximation of the real memory used by my application running with mono, I logged the return value of "System.GC.GetTotalMemory(false)". It is stable while the memory consumption by the mono process increases. I don't know what to try now... Has anyone a hint or tip? Please ask if you need more information. Some additional information: Because I work under Windows XP, my C# code is written and built with Visual Studio 2008 Express Edition. The production environment is a VPS with Debian Etch and Mono version 1.9.1 from http://debian.meebey.net/etch-backports. The VPS is a 64-bit system.
