Hi Team,
This is in continuation with below threads: 1. http://mailman.mit.edu/pipermail/kfwdev/2018-February/date.html 2. http://mailman.mit.edu/pipermail/kfwdev/2018-May/date.html We could get a crash dump for the scenarios explained above. From the dump, below are the observations: 1. The crash is happening within “service_tcp_write” function of “sendto_kdc.c”, while executing the if condition “if ((size_t)nwritten < SG_LEN(sgp))”. 2. The issue doesn’t happen for all the requests, but is frequent in a specific environment. We have not been able to determine a specific pattern yet. 3. The observed values for relevant fields/variables from one of the dumps are as below, all the dumps have the values in same pattern: conn.state = WRITING conn.addr.transport = TCP conn.addr.family = 2 conn.addr.len = 16 conn.out.sgbuf[0] = {len = 4, buff = ‘\0’} conn.out.sgbuf[1] = {len = 1882, buff = ‘some data’} conn.out.sgp = {len=??? buf=??? } conn.out.sg_count = -10339 conn.out.msg_len_buf = "" nwritten = 3199132154 From the values above, it looks similar to the second possibility suggested in http://mailman.mit.edu/pipermail/kfwdev/2018-February/000892.html. However, we do not have any clue yet on what could be causing this. Any help on this will be appreciated. Thanks PS: We are using krb5 tag version 1.16-final ( https://github.com/krb5/krb5/blob/krb5-1.16-final/src/lib/krb5/os/sendto_kdc.c ) Regards, Rama _______________________________________________ kfwdev mailing list kfwdev@mit.edu http://mailman.mit.edu/mailman/listinfo/kfwdev
