FDB test failure is unrelated

Hi @akumar074,
it seems that I have issues with indexing of assets after re-importing of project. Steps to reproduce:

1. Import Mortgage_Process project
2. Delete the project
3. Import the project again
   RESULT:
   

This happens sometimes after first reimport, sometimes after another one, but it seems to be reproducible. Could you please check this?

@akumar074 any updates on this? Today is the freeze for 7.10.1 CR1

Hi @barboras7 I am looking into this, but having a problem debugging. If not possible, we'll have to push it for a later release.

Hi @akumar074,
thanks for the provided .war file. I checked and the issue that I mentioned above is already fixed.

To check the number of open files in the business central, I used lsof -p jps|grep 'jboss-modules'|cut -d ' ' -f 1|grep -c '<pathToFolderWhereBusinessCentralIsLaunched>/.index'.

I tried it multiple times, following are the numbers returned by the lsof command (I used Mortgage_Process project):
9 (before the first import), 25 (after the first import), 25 (first delete), 25 (second import), 25 (second delete), 72 (third import), 40 (third delete), 35, 35, 25, 25, 40, 40, 53, 53, 105, 25, 83, 83, 83.
Are these numbers acceptable? I am not sure if after each delete, we should get to the same number or it's fine that the numbers are increasing a bit.

Hi @barboras7 ,

As I mentioned on the JIRA ticket when you delete a project it is marked as deleted and it is actually deleted after sometime within a minute. Till then the indexes are kept in the .index. After the deletion is done, we have some files deleted but opened in JVM. These files will get cleared after the GC cleans.
To confirm this you can use jvisualVM to clean the GC. you will see the reduced number of opened files then.

Hi @akumar074,
I am sorry, I did not notice the comment. I tried and the files are getting deleted correctly. Thank you.

@akumar074 the FDB error is related to your changes?

[akumar074]

@adrielparedes the failing test isn't related to changes.

[ederign]

@akumar074 do the rename just for master

[ederign]

just a minor rename
