I would like to say i am newbie in mongodb,today i have tried to restore dump file .I am getting the Assertion failure _state.get() during mongorestore dump in my mongod and process has stuck at that time. The mongodb environment is as follows:

Mongodb version is - 3.2.16-11-g1abb660
O.S - Windows 7 Enterprise 32-bit
mongodb is running in Domain account.

As i am sending the below restore dump log from my mongod

I am also attaching the mongorestore dump error & also mongod screen shot

mongorestore dump error enter image description here

mongod error enter image description here

Any help or suggestion will be appreciated.

  • Your picture links does not work. Did you see this in your output ailed with errno:8 Not enough storage is available to process this command? Commented Oct 11, 2017 at 11:21
  • @SqlWorldWide, I have just edited. Could you check you again? Please. May be the site maintenance or else. I also don't know the exact reason. Just i trim the picture size and again upload that. Commented Oct 11, 2017 at 11:43
  • As it is pointed out, you run out of disk space!

  • @JJussi, Approx 200 GB disk space is available . Commented Oct 12, 2017 at 9:05
  • At all your disks? System and data.

1 Answer 1


With a 32-bit O/S the total addressable file size for MongoDB's MMAP storage engine is limited to ~2GB of data including indexes (and journal, if enabled). Given the 32-bit limitations for memory-mapped files, journaling is off by default on 32-bit MongoDB builds as otherwise the data limit would be halved. This is not a recommended configuration for any important data: unclean shutdown is very likely to result in data integrity issues.

The WiredTiger storage engine, which is the default storage engine in MongoDB 3.2 and newer, only supports 64-bit operating systems.

From the log provided it appears that you have exceeded the maximum storage size that can be memory-mapped for a 32-bit server:

2017-10-11T12:40:23.705+0300 I CONTROL [conn13] MapViewOfFileEx for C:\data\db\citibike.2 at address 00000000 failed with errno:8 Not enough storage is available to process this command. (file size is 268435456) in MemoryMappedFile::map

If your database is too large for the limitations of MMAP on a 32-bit O/S, you will have to either do a partial restore or upgrade to a 64-bit environment.

Note: 32-bit server builds were officially deprecated as of MongoDB 3.2 and are no longer available for MongoDB 3.4+.

  • You are absolutely right. As even i also installed 64 bit of MongoDB (ver 3.4) in my laptop and able to restore my "mongodump" there. So, i am going to accept you answer. Commented Oct 12, 2017 at 11:06
