Run time error during variant calling

Hi, I'm using GATK latest version to analyze paired end exome sequencing data. I'd like to see the SNP, Indel and also SVs. I have followed the workflow of GATK, from the duplicates marking to the reads reducing step. Everything goes fine, until I start to use the HaplogypeCaller walker for the variant calling. Command line I used:

java -jar $GATK/GenomeAnalysisTK.jar -T HaplotypeCaller -R human_g1k_v37.fa -I sample_reduced.bam -o sample_variant.vcf

At the beginning, it worked well, then I got the error message of "Reads are too small for use in assembly." And I also tried the UnifiedGenotyper walker, command line:

java -jar $GATK/GenomeAnalysisTK.jar -T UnifiedGenotyper -R  human_g1k_v37.fa -I sample_reduced.bam -glm BOTH -o sample_variant.vcf

I got an error message of "Read bases and read insertion quals aren't the same, size 46 vs. 49". I have googled the error message, but no related result. Does anyone met with the same problem? Eager to know how to solve this. Thanks!
