Error description

  • Informix 12.10 has increased the number of transactions beyond
    the 32k limit that exists in earlier versions. Associated with
    this increased limit is the number of threads that can run
    within the server. However, attempts to connect more than 32767
    users via a TCP network connection or using stream pipes will
    result in errors once the limit of file descriptors within the
    server has been reached. The client may receive an error such as
    -27001 and error messages may appear in the online log. An
    example of such messages:
    
    16:12:41  (35009536) sockets error - registering a file
    16:12:41  listener-thread: err = 0: oserr = 0: errstr = :

Problem summary

Problem conclusion

Temporary fix

Comments

  • Users who need more than 32k simultaneous connections now can
    set "ulimit -n" on OS level to a desirable number to increase
    the number of open file handles we allow.
