>          Issue Type: Bug
>          Components: Library / Graph Processing (Gelly)
>    Affects Versions: 1.15.1
>         Environment: * Flink 1.15.1
>  * Java 11
>  * Gradle 7.4.2

> When the runVertexCentricIteration function is executed twice it will throw an error: 
> java.lang.IllegalArgumentException: Too few memory segments provided. Hash Table needs at least 33 memory segments.
>  
> We solved this issue by setting the following configuration:
> ```
> VertexCentricConfiguration parameter = new VertexCentricConfiguration();
> parameter.setSolutionSetUnmanagedMemory(true);
> ```
>  
> However, the execution times cannot be greater than 4 (>4).  After executing four times it will throw an error: java.lang.IllegalArgumentException: Too little memory provided to sorter to perform task. Required are at least 12 pages. Current page size is 32768 bytes.
