[request-tracker-maintainers] Bug#498692: request-tracker3.6: hangs when displaying merged tickets

[Ansgar Burchardt]

Package: request-tracker3.6
Version: 3.6.7-3
Severity: grave
Justification: renders package unusable

I am using request-tracket3.6 with Apache 2 (FastCGI), Postfix and Postgres
backend.  When trying to display a merged ticket, RT's FastCGI process
just hangs.  This results in RT no longer being accessible over the Web
interface at all.

It still seems to be possible to get some information with the `rt'
command line utility, but the web interface does not work at all.

The following message shows up in syslog:

    Sep 12 11:37:46 bistromathics RT: We found a merged ticket.124/123
    Sep 12 11:38:52 bistromathics last message repeated 177 times

Running strace on the process shows this in a loop:

    time(NULL)                              = 1221214198
    stat64("/dev/log", {st_mode=S_IFSOCK|0666, st_size=0, ...}) = 0
    socket(PF_FILE, SOCK_STREAM, 0)         = 5
    ioctl(5, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfa12528) = -1 EINVAL (Invalid argument)
    _llseek(5, 0, 0xbfa12570, SEEK_CUR)     = -1 ESPIPE (Illegal seek)
    ioctl(5, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfa12528) = -1 EINVAL (Invalid argument)
    _llseek(5, 0, 0xbfa12570, SEEK_CUR)     = -1 ESPIPE (Illegal seek)
    fcntl64(5, F_SETFD, FD_CLOEXEC)         = 0
    connect(5, {sa_family=AF_FILE, path="/dev/log"...}, 110) = -1 EPROTOTYPE (Protocol wrong
    type for socket)
    close(5)                                = 0
    socket(PF_FILE, SOCK_DGRAM, 0)          = 5
    ioctl(5, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfa12528) = -1 EINVAL (Invalid argument)
    _llseek(5, 0, 0xbfa12570, SEEK_CUR)     = -1 ESPIPE (Illegal seek)
    ioctl(5, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfa12528) = -1 EINVAL (Invalid argument)
    _llseek(5, 0, 0xbfa12570, SEEK_CUR)     = -1 ESPIPE (Illegal seek)
    fcntl64(5, F_SETFD, FD_CLOEXEC)         = 0
    connect(5, {sa_family=AF_FILE, path="/dev/log"...}, 110) = 0
    time(NULL)                              = 1221214198
    time(NULL)                              = 1221214198
    select(8, [5], NULL, [5], {0, 250000})  = 0 (Timeout)
    write(5, "<15>Sep 12 12:09:58 RT: We found "..., 57) = 57
    close(5)                                = 0
    time(NULL)                              = 1221214198
