Error connecting to the IO server: o_connect_auth returns -1: Hello request error Error getting conf

Hello,

maybe somebody will be able to help cause solution provided by Automic support didn't help.

Since few months we occur randomly issue with one of our nodes. One or more sessions are Aborted with job log:

"
Error connecting to the IO server: o_connect_auth returns -1: Hello request error
Error getting conf from IO server: o_get_conf_from_io returns -1
Cannot load environment
The syntax of the command is incorrect.
"

In universe.log of node we can find errors like this :

"

Solution suggested by Automic support was:

"
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ SubSystems \ Windows

like this :

%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,20480,1024 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ServerDll=sxssrv,4 ProfileControl=Off MaxRequestThreads=16

and restart the windows server.
"

but didn't help.


Maybe someone had similar issue and can give me possible solution?

Failing node is virtual machine with 64bit Windows 2008 R2 SP1 and $U 6.2.01
The only one UVMS in environment is linux with $U 6.6.01

    Hi Pawel,

    I talked to support guys and it appears that your issue has been transfered to the R&D guys for a root cause analysis.
    If possible, I suggest that you upgrade your DUAS to a more recent version like v6.6.24.
