Hi
We are writing a new server program to receive various IDOC's and function calls from SAP on our MES server.
When SAP tries to download Planned Orders (LOIPLO) type messages we get the following error:
JCO$Exception: (120) JCO_: JCO.Server could not unmarshall tables
The same server program can receive other IDOC's and function cals e.g. LOIPRO type messages without getting the same error.
The only difference is that there are 1975 Planned Orders(LOIPLO) to be downloaded and only one or two Process Orders(LOIPRO).
The errors are as follows:
Exception in server MESPPPISER : com.sap.mw.jco.JCO$Exception: (120) JCO_: JCO.Server could not unmarshall tables
D:\Systems\DMES\Bin>java -jar rfctestserver.jar MESPPPISER BMS2 sapgw02
com.sap.mw.jco.JCO$Exception: (120) JCO_: JCO.Server could not unmarshall tables
at com.sap.mw.jco.rfc.MiddlewareRFC$Server.nativeListen(Native Method)
at com.sap.mw.jco.rfc.MiddlewareRFC$Server.listen(MiddlewareRFC.java:1395)
at com.sap.mw.jco.JCO$Server.listen(JCO.java:7067)
at com.sap.mw.jco.JCO$Server.run(JCO.java:6996)
at java.lang.Thread.run(Unknown Source)
Any help will be appreciated.

afaik this happens if there is not enough memory available for your java program
try to increase the heap size when calling your program
e.g.
java -Xms128m -Xmx512m -jar rfctestserver.jar MESPPPISER BMS2 sapgw02
