The last few weeks I have been getting the following error about every 5 days: 

ERROR: Java heap space

java.lang.OutOfMemoryError: Java heap space

When this happens I cannot access the admin console.
I see the error in the syncrify.log file. 

I feel like it started after updating Syncrify to Version: 6.2 - build 1178

The only resolution I have found is to restart the Syncrify service. 

Allen,

I am sorry to learn you're running into this problem. Hopefully, my response will help you determine why this is happening. Most likely, this problem is not related to the upgrade.

There are two possible reasons for:

1. Max Memory - Your Syncrify server is configured for less memory. Log in as the administrator and refer to the memory graph on the Home page. The red line on that graph represents maximum memory. If this value is around 500 MB, that means your server will not be able to use more than that, even if your machine has significantly more RAM.
2. Data Corruption - When Syncrify Client needs to send any data, such as a string of characters, it first sends the length of that data. Often, firewalls and antivirus software between the Syncrify Server and Client can corrupt the package, resulting in a very long length value, causing unnecessary memory usage on the Syncrify Server. Try disabling packet-level filtering in your firewall/anti-virus to see if that makes any difference.

Let me know if the total memory is low. I will send you the instructions on how to increase that limit.

Memory graph only shows the last hour. It shows Max Memory at just above 450. Allocated Memory ranges from under 250 to almost 350. Used Memory ranges from about 35 to almost 200. If there is a way to adjust max memory that would be great.

We backup to a local hard drive on this machine and have been for a couple years. If the firewall/anti-virus was the problem I would have expected it show up before now.

Hi. Please send the instructions on how to increase the limit.

I apologize for the delay. Please refer to https://web.synametrics.com/increase-max-memory-windows.htm for instructions.
