Not proceeding from "Dremio is starting up"

After I installed dremio and tried to start, the message “Dremio is starting up” is not changing and cannot use.
Referring FAQ(, seems my machine is compatible as follows.

OS:Windows 7 pro
CPU:XEON CPU E3-1225 v5 (think compatible with AVX2)
JAVA:Java SE Development Kit 8u192

Additionaly, I also confirmed the port use with code below.

netstat -an | find “9047”

Before launching dremio, it returns nothing, however, while dremio is executed it returns “SYN_SENT”.
I will attach logs too. (2.3 KB)

Could you please let me know how can I proceed.

Hi @john_doe

Looks like from your server.out you are getting a Java core dump and core has not been enabled. What is inside “C:\Program Files\Dremio\hs_err_pid5228.log”?

A fatal error has been detected by the Java Runtime Environment:

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000007fefd8fb2b2, pid=5228, tid=0x00000000000012c0

Java VM: Java HotSpot™ 64-Bit Server VM (25.192-b12 mixed mode windows-amd64 compressed oops)

Problematic frame:

Hi Balaji,

Thank you for supporting and apologies my reply being late.
Please confirm with the file I attached.
Note that I’ve re-installed Java environment and dremio which might change the log though i’m still falling into the same situation.
I will attach the server file and the “err” file.
Hope this will help you.

Hi @john_doe

Is see the total RAM on the box is 16GB. Have you changed anything on the dremio-env? In other words what are the memory settings on dremio-env?


Hi @balaji.ramaswamy

Thank you for confirming.
I have not changed anything.

Have you changed anything on the dremio-env?

And for the question, am I right to check the file “C:\Program Files\Dremio\bin\dremio-config”?
If yes, please confirm with the file I attached.
Hope this will help you. (3.0 KB)
