c++ - mmap call takes too long (>100 seconds) -

-

We are currently looking at taking our processes with the mmap call for a very long time. Once the process reaches approximately ~ 2.8 GB, the MMAP takes the call to 100 seconds and is killed by the heart beat mechanism created in this process. Anyone would like to know this problem or will know why it will take more than 100 seconds when asked for memory.

Host and compiler information:

  • Host memory: 70 GB OS: All files, Redhat 6.3 compiler: GCC 4.4.6 process memory limit (32 bit): 4 GB no swap configured

And if this happens, the host still has 50GB of storage remaining.

One by name table, Table 2 h Yes TableOnEID = @Pharmak "* / for (Int Index = 0; Index and Lt; ParamariX Parameter (.c calculation; Index ++) Cmd.Parameters.AddWithValue (paramQuery.Parameters ().

ElementAt (index) .Value = "tableTwo.ID" * / MySqlDataReader Reader = cmd.ExecuteReader (); While (reader.Read ()) {// do stuff} } One of the tables I attempt to join is For the table, two with the same id for all. Is there something that I'm doing wrong?
