smbd is very unstable for me, usually crashing when a client connects. A typical stack trace goes like this: 0x8186736: file lib/fault.c, line 50. 0x818682d: file lib/fault.c, line 136. 0x81869fc: file lib/fault.c, line 157. 0xffffe420 0x81163db: file heimdal/lib/gssapi/copy_ccache.c, line 158. 0x81ffa1b: file auth/credentials/credentials_krb5.c, line 556. 0x8418215: file auth/gensec/gensec_gssapi.c, line 180. 0x836a6c3: file auth/gensec/gensec.c, line 479. 0x836a938: file auth/gensec/gensec.c, line 554. 0x84135d0: file auth/gensec/spnego.c, line 433. 0x8413d22: file auth/gensec/spnego.c, line 616. 0x836b063: file auth/gensec/gensec.c, line 757. 0x81ec6c9: file smb_server/smb/negprot.c, line 373. 0x81ec99d: file smb_server/smb/negprot.c, line 475. 0x81eb4a3: file smb_server/smb/receive.c, line 553. 0x81eb9ea: file smb_server/smb/receive.c, line 155. 0x835e100: file smb_server/smb_server.c, line 59. 0x836b75e: file lib/stream/packet.c, line 374. 0x835e1e8: file smb_server/smb_server.c, line 94. 0x82d8f0a: file smbd/service_stream.c, line 93. 0x82de69f: file lib/events/events_standard.c, line 286. 0x82de867: file lib/events/events_standard.c, line 623. 0x82dda2f: file lib/events/events.c, line 157. 0x805c55f: file smbd/process_standard.c, line 108. 0x82d9199: file smbd/service_stream.c, line 193. 0x82de69f: file lib/events/events_standard.c, line 286. 0x82de867: file lib/events/events_standard.c, line 623. 0x82dda2f: file lib/events/events.c, line 157. 0x80573b4: file smbd/server.c, line 251. valgrind shows that the problem is routines trying to access already-freed memory (a static Kerberos context), which is freed in standard_accept_connection(), smbd/process_standard.c:86: talloc_free(ev); If I comment out this line, everything is fine (and all the valgrind hits related to this seem to disappear), but I'd guess that's not the correct solution. :-)
01:20 <@abartlet> Sesse: I pushed some calls around, and it should be correct now I haven't seen it for a while. Closing.
