[...OOPS deleted...] > ohwell :( After finding time to analyze this problem it is clear that the peer sent an invalid response-cookie, which caused this node to crash. We understand what happened there: drbdd -> receive_block_ack -> drbd_end_req -> struct Drbd_Conf* mdev = drbd_conf + MINOR(req->bh->b_rdev); ^^^^^^^^^^ The crash happens while dereferencing req->bh The register holding req (%esi) has 0xffffffff . This req comes from the peer, it got it with the request to write a block. Either your peer is corrupting its memory (more probabely), or the node, on which the OOPS happened is corrupting its memory (less probabel) Please go and get new hardware. [In case memtest86 does not find anything, it could be that the IO operation to disk does the memory corruption...] -philipp -- : Dipl-Ing Philipp Reisner Tel +43-1-8178292-50 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schönbrunnerstr 244, 1120 Vienna, Austria http://www.linbit.com :
