Describe the bug
Using eventgenx feature "extendIndexes" to run with 900 indexes for one sample, I saw memory increase.
(in 16 hours it increased from 300MB to 4GB)

**Expected behavior**
Memory usage should be stable.
**Actual behavior**
Memory usage increase from 300MB to 4GB in 16 hours. And then my container exited by OOM problem.
**Screenshots**
If applicable, add screenshots to help explain your problem.
**Sample files and eventgen.conf file**
Please attach your sample files and eventgen conf file
**Do you run eventgen with SA-eventgen?**
No
**If you are using eventgen with pip module mode (please complete the following information):**
- python version: [e.g. 2.6]
- OS: [e.g. Windows10]
- Virtual Env is used: Yes/No
- Eventgen Version [e.g. 6.3.2]
**Additional context**
Add any other context about the problem here.
This was caused by bugs in extendIndexes feature. Every time the generator calls "loadSamples" function will trigger eventgen to append indexer list to each samples, which makes memory increase.
