NetXMS Support Forum

Hi,

yes, I think you can delete c:\netxms\bin\jre. I have no idea why it was not working when installed into same directory. But we are going to merge server ad web UI installers into one anyway in version 4, so it should not be an issue after that.

Best regards,
Victor

Also found this thread: https://stackoverflow.com/questions/63012015/jni-createjavavm-fails-with-adopt-openjdk-11-0-8. Do you have JAVA_HOME environment set? If yes, try to remove it completely (preferred) or point to C:\NetXMS\bin\jre.

Very strange, I just did the same and service started correctly, so it somehow related to environment. Try to install Java 11 from AdoptOpenJDK separately - maybe we miss something when pack embedded JRE. Those are log lines that are most suspicious:

[2021-04-14 09:41:19] [error] ( javajni.c:828 ) [10492] CreateJavaVM Failed with error [-1]
[2021-04-14 09:41:19] [error] ( javajni.c:828 ) [10492] Das System kann die angegebene Datei nicht finden.

Изменилось ли что-нибудь после обновления на 3.8.262?

Did you change service to run under "Local System" after clean install?

Hi,

it seems to be related to how underlying framework (Eclipse RAP) handles time zone settings provided by browser. I will investigate it further.

Did you tried connecting from different browser? If you set workstation to other UTC-7 time zone without DST, will both desktop and web client show correct time?

Hi,

attached is corrected MIB file. Problem was with some object identifiers starting with capital letter. Standard does not allow object identifiers to start with capital letter, but many vendors does this anyway.

Did you install it on top of old version? If yes, try to remove it and do clean install (make sure to manually delete all remaining work directories after uninstall). Select bundled JVM when installing.

Не совсем понятно о чем именно идет речь. Можно поподробнее описать где что было до того как пропало?

Самое простое - увеличить размер колонки vendor в таблице node_components. Например так:

ALTER TABLE node_components MODIFY COLUMN vendor varchar(127) NULL;

Увеличит размер до 127 с текущих 63.

Или подождать до следующего патч релиза - я добавил контроль длины значения при записи в эту таблицу, слишком длинные значения будут обрезаться.

Hi,

log file just states that service cannot be started. Is there any other log files?

Hi,

it should work, although we didn't test it specifically on that version. Just report here if you will encounter any issues.

Hi,

it was supposed to be in separate deb package, but it was not published. We will publish it in a few days.

Hi all!

We just published new patch release for version 3.8 (3.8.267). Only server and web API are affected. Changes since release 3.8.262:

- Fixed server crash during scheduled task processing
- Fixed issues:
        NX-2009 (Add notification channel driver "Shell command")
        NX-2035 (Instance discovery using ICMP.Targets list crashes server)
        NX-2037 (Save IP address of client connecting via WebAPI to audit log)

Hi,

most likely you have hit RAM limit when allow thread pool to grow to 4000 threads. Could also be other memory-related issue (memory leak in server, slow database causing DB writer queues to grow, etc. Do you have pre-crash data on number of threads, queues, and memory consumption?

Also, 4000 nodes is not that much, it is quite strange that 500 threads is not enough. Such high load on poller pool indicates that there are lot of polls taking long time to complete.  Could it be that you have many nodes that timeout when polled?

Best regards,
Victor
