When using IB Gateway in connection with MultiCharts 64, I do not get access to the historical market data farm and the status indicator for historical data shows permanently red. Real time data works fine. With TWS, I do not have this issue at all. This issue occurred for the first time around...

Finally, IB has issued a fix for the Java memory leak issue with TWS beta 940.1p: http://www.elitetrader.com/vb/showthread.php?s=&threadid=222594&perpage=6&pagenumber=40.

This is very good news indeed. I did some time testing with browser based TWS beta 940.1p and Multicharts64. The memory leak issue seems to be resolved, as javaw.exe size stays around 300 MB for hours. I hope the standalone version will show the same behavior with this fix ported to them. Thanks...

I already did this and submitted a log. Just wanted to know if anybody else has experienced this issue.

Since around two days, I do not get any connection to Historical Data Farm, please see the attached screenshot of IB Gateway (in TWS it's the same problem). I never had this issue before. Any suggestions are welcome.

I had another test with these parameters. With this setting, Gateway crashes after some hours as well, after memory usage gets to around 1.1 GB. For some reason, when I try to open the log file with HPjmeter, I get the failure message below.

And here is the heap usage for Gateway 932.4, for completeness. With this version, Java garbage collection works as it should and no freeze occurs.

Files size of the log file was too big. Another try with zip:

ddecker, below is the log for IB Gateway 938.1f. I'll have another test with the parameters you suggested.

Below is the heap usage for IB Gateway 938.1f (Java version is 1.7.0_21 64 bit and OS is Windows 7 64 bit). The log shows a very similar behavior compared to TWS. After around 8.000 seconds of operation, when the -Xmx1G limit is reached, the Gateway freezes. Start parameters are...

Below is the heap usage log of TWS 938.1f on Win 7 64 bit with Java 1.7.0_21, API client is Multicharts 64. TWS froze after 3 hrs. The log shows that heap usage is constantly growing when TWS runs. I used the following parameters for TWS: C:\Windows\System32\javaw.exe -cp...

pfranz, maybe the issue occurs only for the specific combination of Multicharts and TWS/Gateway 933+? But that's pure speculation, I didn't try any other API client than Multicharts yet.

I tried to integrate the Java log commands you suggested into the TWS shortcut target field, but there is a limitation of characters. Then I tried to start TWS via batch file, but I am not sure how to set the Java class path correctly. I will have another try later on.

Yes, it's not real tick data, but more a "consolidated" datastream that updates every few seconds.

Maybe you want to try to plot in your application some charts of tick data for some Futures intruments (CL, GC, YM etc.) with a historical data range of at least several days, since I have experienced the issue only under these specific conditions. I made some test runs on a dissimilar Win...
