| Solution ID | sk103773 |
| Date Created | 2015-01-13 |
| Last Modified | 2015-01-14 |
| Technical Level | Advanced |
| Products | Multi-Domain Security Management Server |
| Versions | R82.10, R81.20, R82 |
| OS | Linux, Gaia |
| Platform | Smart-1 |

## Symptoms

- * Repeatedly not possible to connect with SmartDomain Manager to Multi-Domain Security Management Server.

* Output of *mdsstat* command repeatedly shows that FWM process in the MDS context is '`Down`' or '`N/A`'.

* Output of *strace* tool shows the following for the time of the issue:

  ```
  
  ... ... ... ...
  unlink("/opt/CPmds-R77/conf/mdsdb/CPMILinksMgr.db-journal") = 0 
  N  fcntl64(85, F_SETLK64, {type=F_RDLCK, whence=SEEK_SET, start=..., len=...}, 0x...) = 0 
  N  fcntl64(85, F_SETLK64, {type=F_UNLCK, whence=SEEK_SET, start=..., len=...}, 0x...) = 0 
  N  fcntl64(85, F_SETLK64, {type=F_UNLCK, whence=SEEK_SET, start=0, len=0}, 0x...) = 0 
  N  gettimeofday({..., ...}, {0, 0}) = 0 
  N  mmap2(NULL, ..., PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE, -1, 0) = -1 ENOMEM (Cannot allocate memory) 
  N  mmap2(NULL, ..., PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE, -1, 0) = -1 ENOMEM (Cannot allocate memory)

  N  mmap2(NULL, ..., PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory) 
  N  write(19, " FwScope::FwScope: Failed to cre"..., 47) = 47

   N  --- SIGSEGV (Segmentation fault) @ 0 (0) --- 
  M  +++ killed by SIGSEGV (core dumped) +++ 
  ```

* Debug of FWM process (per [sk33208](http://supportcontent.checkpoint.com/solutions?id=sk33208)) shows the following for the time of the issue:

  ```
  
  ndb: database not opened
  FwScope::FwScope: Failed to create hash table
  ```

## Cause

FWM process on MDS Server continuously crashes (and is not always restarted after the crash) due to a corruption in the *$MDSDIR/conf/mdsdb/CPMILinksMgr.db* file.
