Hi and thanks for reading,

I have the following error while running my program and can't figure out what the solution would be. I also looked at all the topics with a similar error here, but could not resolve my issue. Here the error:

```
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007f0b024734cd, pid=21947, tid=139676677560592
#
# JRE version: 6.0_15-b03
# Java VM: Java HotSpot(TM) 64-Bit Server VM (14.1-b02 mixed mode linux-amd64 )
# Problematic frame:

```

My program takes some serialized objects and deserializes them, this is where the problem occurs. The strange thing however is, that the same code with the same objects to deserialize works perfectly fine on other machines with the same hardware, OS, etc. (I'm not sure if this might be hardware related, but I guess its not). 

Here is the code, that I'm executing in Java:

```
        FileInputStream f_in = new FileInputStream(path+"/"+docNum+"/"+docNum+"Part.data");
        ObjectInputStream obj_in = new ObjectInputStream (f_in);
        Object obj = obj_in.readObject();
    //ERROR
        FileInputStream f_in5 = new FileInputStream(path+"/"+docNum+"/"+docNum+"Part_clustIdx_pairClustIdxs_.data");
        ObjectInputStream obj_in5 = new ObjectInputStream (f_in5);      
        Object clustIdx_pairClustIdxs = obj_in5.readObject();

        FileInputStream f_in4 = new FileInputStream(path+"/"+docNum+"/"+docNum+"Part_pairClustIdxs_pairPartRootNodeIds_.data");
        ObjectInputStream obj_in4 = new ObjectInputStream (f_in4);      
        Object pairClustIdxs_pairPartRootNodeIds = obj_in4.readObject();

        FileInputStream f_in3 = new FileInputStream(path+"/"+docNum+"/"+docNum+"Part_clustIdx_partRootNodeIds_.data");
        ObjectInputStream obj_in3 = new ObjectInputStream (f_in3);      
        Object clustIdx_partRootNodeIds = obj_in3.readObject();

        FileInputStream f_in2 = new FileInputStream(path+"/"+docNum+"/"+docNum+"Part_rootNodeId_Part.data");
        ObjectInputStream obj_in2 = new ObjectInputStream (f_in2);
        Object rootNodeId_Part = obj_in2.readObject();  

        Part part = (Part) obj;
        part.rootNodeId_part_ = (Map<String, Part>) rootNodeId_Part;
        part.clustIdx_partRootNodeIds_ = (Map<Integer,TreeSet<String>> ) clustIdx_partRootNodeIds;
        part.pairClustIdxs_pairPartRootNodeIds_ = (Map<Pair<Integer,Integer>,Set<Pair<String,String>>> ) pairClustIdxs_pairPartRootNodeIds;
        part.clustIdx_pairClustIdxs_ = (Map<Integer,Set<Pair<Integer,Integer>>> ) clustIdx_pairClustIdxs;   

```

The error occurs after the first deserialization block. However, if I interchange it with any of the following blocks, the error is still in the second deserialization block. Again, the same code, with the same data works just fine on other machines. I tried reinstalling and updating Java, but it didn't help. 

Here the logfile of the error:

Thanks for your help!

As suggested by the posters, it does sound like a hardware problem. I have changed the memory parameters of java and after some changes the program stops at different parts. I will investigate the diagnostics proposed below. I'll give an update as soon as I've done that.

@[egridasov](https://stackoverflow.com/users/811535/egridasov), I tried JRE 1.6.0\_26, but get the same problem:
