Hello, We've been using UML to run some computational applications (developed in-house). The application runs fine for nearly 24h, then is killed with signal 9. Just before the application is killed, these lines appear on the console:
[102159.270000] do_syscall_stub : ret = -12, offset = 1052688, data = 00000000f7b7c010 [102159.270000] do_syscall_stub: syscall 9 failed, return value = 0xfffffffffffffff4, expected return value = 0x173d4000 [102159.270000] syscall parameters: 0x173d4000 0x1000 0x7 0x11 0x4 0x6da32000 [102159.270000] Failed to flush page for address 0x173d4000 So my guess is that the appliaction triggered some sort of "internal error" and was killed by the UML kernel. Googling the error message, I found this reference to an older thread on this mailing list: http://www.mail-archive.com/user-mode-linux-devel@lists.sourceforge.net/msg04364.html I'm not sure what is meant there with UML "exceeding 256M RSS" and how/if this can be worked around. The UML machine is launched with "mem=2G" and the application is expected to use about 1G max. Any suggestion? For the record, we're using UML 2.6.38.4 (from devloop.co.uk) with a Debain 6 (squeeze) FS (installed via Debian's rootstrap).
