    Hi Stijn,

    First of all ... I wish you a .. HAPPY NEW YEAR !

    This error means that DQM is not able to create (fork a process in unix) a child process for a new launch , this might happen when one of the ressource limits of the uxdqmsrv engine, or of the user running DQM is reached ( number of processes, memory to be allocated to the new process, file descriptors ... ).

    is your DQM heavy loaded ?

    Regards,

    Kamel

    Is this is $U problem or server problem ?

    Hi Stijn,

    This is not a $U problem,
    It is a general sizing problem, between instant load and available ressources on the server  allocated to the user.
    when you have an edge of simultaneous submission that exceeds the limits allocated, you get this kind of error.

    2 combinated actions are useful :
    - adjust the resources allocated to the load
    - regulate the instant load to the available ressources

    Regards

    Kamel

    1) increasing the ressources allocated

    The ulimit command for the account running DQM,  usually the same account running $U, will help you .
    "ulimit -Ha"  for the maximum available ressources on the server for a user
    login as the account running $U, then run  "ulimit -a" to see the allocated ressources to this account. 
    your system administrator can increase the allocations.

    2) adjusting the instant load in order to regulate the charge will reduce/eliminate the edges.
